Title: Target structure for single tube type colour television cameras
IPC: H01J31/46
Filed: 1973-10-11
Abstract: 1417785 Image pick-up tubes; semi-coriductor devices MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 11 Oct 1973 [11 Oct 1972 25 Sept 1973] 47514/73 Headings H1D and H1K A target for a colour television camera tube includes a semi-conductor wafer 20 having an array of regions 22 of opposite conductivity type, and on the opposite surface a plurality of impurity doped regions 21, 23, and 25, repeated in sequence across the target, for separately controlling the diffusion to the regions 22 of carriers generated in the wafer at different depths by light of different wavelengths in an optical image incident on the target. As described, wafer 20 is N-type silicon of 5 to 10 ohm centimetre resistivity, while regions 22 are P-type; regions 21 are phosphorus doped N- type of 5 Î 10<SP>19</SP> to 1 x 10<SP>20</SP> atoms cm.<SP>-3</SP> and 0À1 to 0À3 Ám depth; regions 23 are boron doped P- type of 1 Î 10<SP>20</SP> to 9 Î 10<SP>20</SP> atoms cm.<SP>-3</SP> and 0À1 to 0À5 Ám depth; and regions 25 are similar to regions 23 but are of 1 to 5 Ám depth. The donor-doped regions 21 reduce loss of blueinduced carriers at the surface of the wafer 20 by lowering the surface recombination at that surface, whereby the signal x 1  obtained from the opposed junctions 22 represent blue+green+ red. The acceptor doped regions 23 increase the surface recombination, thereby removing the blue-induced carriers such that the signal x 2  from the opposed junctions 22 represent green + red. Similarly, the deeper acceptor-doped regions 25 also remove the green induced carriers, providing a signal x 3  representing red only. The blue, green and red colour signals are derived from signals x 1 , x 2 , and x 3  by appropriate subtraction. The triads 21, 23, and 25, which may be dots or stripes, are separated by index regions 28. Layers 24 and 27 are of silicon dioxide covered, respectively, with a (unspecified) resistive layer 26, and an antireflection layer 29 formed by phosphorus silicate glass sandwiched between silicon dioxide layers.

Abstract: 1331307 Flash discharge apparatus WEST ELECTRIC CO Ltd 16 Oct 1970 [20 Oct 1969 (3)] 49190/70 Heading H2H Flash discharge apparatus wherein a capacitor is discharged through a gas discharge tube to produce illumination is provided with means whereby the degree of illumination produced by the tube is controllable. A capacitor 1 is charged from a source 10, 11 and is discharged through a zenon discharge tube 2 when a potential is applied to the starting electrode thereof by closure of a switch 7. Initially the discharge of the capacitor through the tube passes through the variable resistor 3 the value of which is such that the illumination of the tube 2 is low. If, at a desired instant, a thyristor 5 is rendered conductive and part of the resistor 3 is shortcircuited, the energy which remains in the capacitor 1 passes through the thyristor 5 to produce a flash of light from the tube 2 the intensity of which is determined by the instant at which the thyristor 5 is rendered conductive which in turn is determined by the settings of variable resistors 3, 8. Thus the intensity of the illumination produced by the tube 2 is variable as desired by adjustment of the resistors 3, 8. In another embodiment an initial flash of light is produced by the tube 2 for range-finding purposes and the reflected light used to control the intensity of the illumination produced by the tube. Thus, in Fig. 3 discharge of a capacitor 22 causes the tube 23 to illuminate an object and the reflected light is received by a photoconductive element 34 which controls the charging time of a capacitor 36. The charge in this capacitor controls the conduction of a transistor 31 and thereby the gate potential of a thyristor 28 which thyristor becomes conductive at a time determined by the range of the object so producing a flash of light from tube 23 of an intensity required by the range. In another embodiment two flash tubes are used.

Abstract: 1,083,266. Magnetometers. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 8, 1964 [Dec.12, 1963], No.49947/64. Heading G1N. A magnetometer for use on board a movable body (e.g. an aircraft or missile) comprises two nuclear magnetic resonance generators 1a, 1b each coupled to a respective system 2a, 2b of subatomic particles (e.g. protons) having a gyromagnetic ratio different from that of the subatomic particles (e.g. fluorine, phosphorus or helium 3 nuclei) of the other system and means for forming a signal of frequency equal to the algebraic difference of the frequencies of the generators which frequency is proportional to the intensity of the magnetic field to be measured and is independent of the rotation of the systems with respect to the magnetic field. As shown, system 2a contains Fremy salt dissolved in water and system 2b, which is rigidly attached to system 2a, contains Fremy salt dissolved in meta C 6 H 4 (CF 3 ) 2 . Oscillator 6 and coils 4a, 4b saturate the 56 Mc/s electronic resonance line of the Fremy salt to enhance, by the Overhauser- Abragam effect, the magnetic resonance signals from the protons in system 2a and the fluorine nuclei in system 2b. Pick-up coils 8a, 8b surround systems 2a, 2b respectively and each forms part of a resonant circuit, e.g. 8a, 10a, tuned to the Larmor frequency, connected to a linear amplifier 11a. Part of the output of the amplifier is fed back through resistor 13a and a balancing potentiometer 14a to a coil 9a whose axis is perpendicular to that of coil 8a so that coupling between these coils occurs only through the nuclear magnetic resonance. A mixer 15, which is described with reference to Fig. 2 (not shown), forms the sum and difference of the Larmor frequencies and a band-pass filter 16 passes only the difference frequency to a frequency meter 17 and a recorder 18. In a modification, system 2b contains phosphorus nuclei in sodium metaphosphate. In another modification, helium 3 nuclei are used in system 2b with optical pumping. Other generators may be used such as the maser type or the free precession generator, both described in Specification 1, 076, 700. Instead of Fremy salt, it is possible to use diphenylpicrylhydrazyl or a radical comprising a nitroxide group linked to two carbon atoms each in turn linked to three other carbon atoms.
